“…This could be refiected in the present alteration noted in sporophore production, as the species composition changes markedly between the zones (Ohtonen et al, 1990). The correlation between below-ground fungal structures, i.e.…”

“…The mean of the inventories in the years 1988-90 was used as the estimates of sporophore biomass of both mycorrhizal and saprotrophic fungi. The results were analysed together with the properties of the humus layer and certain biological parameters obtained earlier for the same sites (element concentrations in the forest humus, soil respiration, microbial biomass and the amount of FDA active hyphae in the soil; Ohtonen et al, 1990;Ohtonen & Markkola 1991;Ohtonen, 1994) using one-way ANOVA, Tukey's test, linear correlation and regression analyses and principal component analysis (PCA) as contained in the SAS statistical package (SAS Institute Inc., Cary, N.C, USA). As there were violations of the basic assumption of homogeneity of variances even after log-transformation of the sporophore data, a non-parametric Kruskal-Wallis test was used for al!…”

“…The rate of litter decomposition has been infl uenced by the accumulation of Cu, Ni and Zn in brown needle litter and root litter, collected at the site (McEnroe and Helmisaari 2001, Nieminen andSaarsalmi 2002). The accumulation of metals into decomposing unpolluted needle litter was also observed thus retarding the decomposition rate near the smelter (Ohtonen et al 1990). …”
